Cleaning sunscreen residue on metal
I’m new in formulating, and currently i work for physical sunscreen formulation. I was practicing on making water resistance w/o physical sunscreen. the formulation contain Titanium dioxide as the main UV filter, and after making the batch using big stainless pot (5 kg batch size), i found some trouble when cleaning the pot after i left the dirty pot for several hours using dish-washing soap. I also found similar residue while making vanishing cream with high TiO2 content, meanwhile i don’t find this problem while making other formulation
does anyone has any suggestion on why this could happen? and how to clean TiO2 residue on stainless or any other metal?
do i need to use specific material or methods to remove this kind of residue?

No offense but people “new to formulating should NOT, absolutely NOT attempt to make an SPF product. There are numerous posts from experienced Formulators echoing this sentiment.

hiii, thank you for the concern. just to clarify, i think i made mistake on my description because this is my first time posting
i wasn’t making my own formula, i was practicing on making all type of formulation using my senior’s formula. when i find any problem they said that i should look for the answer on my own first before the discussion, that’s why i try to ask heree

The go-to alkaline cleanser all of us formulators use is Alkanox. This will clean your pot. Someone told me they even saw it in Lowes but I doubt that. You can buy it through lab supply houses (VWR) and through industrial supply houses (McMaster & Carr, W. Grainger)
